This invention relates generoiiy to'refrigerstor cabinets snot refers more perticuisriy to those uesigneci for-use Within wells or cupboards.

Heretofore it has been customary when insteiiing refrigerating apparatus on onin reirigereting cohinets to mount the refrigerant ion! side such as the cooiing coils or chamber Within the foodcompartment or in c cooling chamber of the cabinet and to mount refrigerant high side such as the compressor and concienser either on top or at the hottom of the cabinet @rdinariiy it was cihiicuit to instnii the machine upon or remove it from the top of the cabinet. in fact, it has been necessary sometimes tense cierr s snot/or cranes to efiect the desireci instoi tion remove ii of the high sicie ports. The space occupieci was great since it was necesserv to show not only the ectuei spece requires; by the cabinet enct machine, hut eiso suf icient spece for instoiiing or removing e machine ierge specetor sir circuiotion, especiniiy whereconvecticncurrents in the air were depeutieci upon. Moreover, t? e space shove the cshinet about the opper tus couici not he used setisifcct'oriiy es cc. inet or cupboard. spnce, hence was westecin En eoitiition such insteiietions usuo iy inciucieci iJOX-iikh covers or cages for the i q rnech re, and such enciosures were unsightiy. Vr pieced ct bottom of the cehinet the machine occupieci space which might P othertviseheve been usetui for cuphoord space or for receiving foods, and from on ehiciency standpoint Wes objectionable, Due to the iocetion enci arrangement of ports the entire machine couici not he instoiieoi in or reniovefi rorn the cabinet without rocking hresi ng pipe connections, the con sequent chences of gas anti oii escaping or ti cnri moisture entering the system, This eonireri shiiied workmen. "in fact such orhmen had; to ieeve the service station or actor trovei to onri from instaiietions not nierehy consorneti such time in just es truck drivers heck anti forth jobs. Consequentiy such workmen were to devote their entire time to skiiieti Work and Were expensive to tein.

With the present invention, however, the cabinet receives both the high one; iovv sioies of the apparatus and also receives air from the atmosphere for cooiing the high siie enoi eflecting the desired. condensetion oi"- the re frigerent therein, hence my improved construction obviates the necessity for space on top, about or at the bottom of cuhinet for refrigerating apparatus. Moreover, cabinet fit snugiy Within openino; of suiostentieiiy corresponding size in e or cuphosrri end the Eoooi cornpertinent anti cupboard space is ohteineci,

Reterrin now to the drawings, 1 is c cehinet etieptecr to snugiy within on opening or? suhstentieiiy corresponciing size in s wait. or cupboard and having on open top chant her 2", for refrigerating apparatus and compertrnent 3 for :tooci, As shown, the chemconstruc e 6 is top view of the conher 2 projects forwardly from the rear wall 4 of the cabinet adjacent the top wall 5 and has an opening 6 in its front wall 7, while the food compartment 3 is in front and below the chamber 2 and has an opening 8 in the front Wall 9. The base 10, compressor 11, motor 12, fan 13, condenser 14 and expansion valve 15 of a portable refrigerating apparatus such as that set forth in my companion application Serial No. 440,558 are received within the chamber 2, while the cooling element 16 of the apparatus is received Within the food compartment 3 and has a tray compartment opening 17 in its front wall adjacent the opening 8 in the front wall 9. The trim panel 18 between the cooling element 16 and the base 10 of the portable apparatus normally closes the opening 6 in the chamber 2, while a door 19 closes the opening 8 in the front wall 9. Preferably the door is received in the opening 8 in the front wall so that the inner face 20 thereof closes the tray compartment opening 17 in the cooling element, and the outer face 21 thereof is substantially flushwith the outer face 22 of the wall 9. Thus the construction of the chamber 2 and the location of the opening 6 in the front wall thereof relative to the opening 8 in the front wall of the cabinet is such that the portable apparatus may be easily and conveniently moved through the opening 6 in the front wall of the cabinet to or from the chamber 2. This is one of the features that enables the cabinet to fit snugly within an opening in a wall or cupboard.

In the present instance the door 19 and the front wall 9 at the sides and bottom of the opening 6 are provided between their inner and outer faces with bodies 23 and 24 respectively of insulating material such as cork. Above the opening 6 the front wall 9 has a bar 25 of wood that is spaced from the top wall 5 and is terminally connected to the side walls 26 and 27 respectively. Preferably this bar 25 is provided throughout its length with a substantially L-shaped rabbet 28 that opens upwardly and outwardly and receives an electric switch or cold control 29 for the motor 12 in the chamber 2. This switch 29 is mounted in the front wall 9 opposite the center of the bar 25 and is connected by suitable conductors (not shown) to the motor. A partition 30 havin a body 31 of insulating material extends orizontally between the bar 25 and the front wall 7 of the chamber in spaced relation to the top 5 and constitutes a portion of the ceiling of the food compartment 3. The bottom 32 of the chamber constitutes the other portion of the food compartment ceiling.

Preferably the bottom 32 of the chamber 2, the upright wall 33 carried by the refrigerating apparatus base 10, the bottom wall 34 of the cabinet, a portion 35 of the rear wall between the chamber bottom 32 and the bottom wall 34 of the cabinet, and portions 36 and 37 respectively of the side walls 26 and 27' located in front of and below the chamber 2 contain insulating material such as cork. Thus the food compartment 3 is insulated from the chamber 2 and from the outside atmosphere. Moreover the inner faces 41, 42, 43, 44, 45, 46 and 47 respectively of the door 19, partition 30, trim panel 18, chamber bottom 32, side wall portions 36 and 37, and rear Wall portion 35 are porcelain and provide a neat sanitary and attractive appearance.

In order that the refrigerating parts such as the condenser 14, compressor 11, etc., within the open top chamber 2 may be effectively cooled by fresh air from the atmosphere, the front wall 9 is provided above the opening 8 upon opposite sides of the switch 29 with laterally spaced louvers 48 and the space between the horizontal partition 30 and the top 5 of the cabinet is divided by a vertical partition 49 into two passageways 50 and 51 respectively whereby air from the atmosphere may be drawn by the fan 13 through the louvers 48 upon one side of the switch 29 and through the passageway 50 to the open top chamber 2 and will be forced by the fan through the chamber 2 and thence outwardly through the passageway 51 and louvers 48 upon the other side of the switch. Hence air for cooling the refrigerating apparatus and effecting the desired condensation of refrigerant in the condenser 14 is drawn through and discharged from the front wall 9 of the cabinet. This is another of the features that enables the cabinet to fit snugly within an opening in a wall or cupboard. In this connection air from the atmosphere may be directed to and from the chamber 2 by other means such as conduits (not shown) extending through the flooring (not shown) upon which the cabinet rests or is supported. Preferably the partition 49 extends between the front and rear walls 9 and 4 respectively of the cabinet and is provided at its rear end with a depending portion 52 that serves as a vertical partition in the upper )ortion of the chamber 2. A second verticalpartition 53 overlaps this depending portion 52 and cooperates therewith to cause air from the passageway 50 to pass downwardly and through the condenser 14 and about the motor 12 and compressor 11 before passing outwardly through the passageway 51.

In Figures 9 and 10 I have illustrated a modified construction in which the louvers 60 extend horizontally and open downwardly and constitute outward embossed portions of a sheet metal plate 61 secured by screws 62 to the front of the cabinet.

While it is believed that from the foregoing description the ,nature and advantages of the invention will be readily apparent, I desire to have it understood that I do not limit myself to what is herein shown and described and that such changes may be resorted to when desired as fall within the scope of what is claimed.
